WALLACE WHITE, OF LAWRENCE, MASSACHUSETTS.

RErINING-ENGINE.

To all whom it may concern.'

Be it known that I, WALLACE WHITE, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Refining-Engines, of which the following is a specification.

This invention relates to refining engines of the Jordan type, and particularly io the filling blocks or pieces which are interposed between the blades or knives thereof. So far as I am aware, these filling blocks have been made of wood, several superimposed strips being usually employed in their manufacture. The wood absorbs the liquid ingredients of the stock, and said ingredients are of such a character that the wood soon becomes soft and yielding and consequently does not hold the blades as rigidly as is required for the production of the most efficient results. The tops of the filling blocks, which are exposed to the stock passing through the engine, necessarily soften first and cease to form rigid abutments or side supports for the blades, so that the blades have a tendency to tip slightly, and as the depth of the yielding portions of the blocks gradually increases the supporting power correspondingly decreases. The blocks thus softened or having yielding tops, when employed to resist the severe strains of the blades, rapidly deteriorate, and furthermore, are easily injured by the hard foreign substances which often times nd their way into the stock, so that in addition to being ineffective as a means of supporting the blades they are short lived.

This invention has for its object to construct a filling block which overcomes the above noted objections to the wooden block.

rlhe invention also has for its object to provide improved forms of wedges for holding` the blocks and blades assembled.

Fioure l shows a portion of the shell and plug of a Jordan engine having fillingblocks between the blades, embodying this invention. Fig. 2 is a sectional detail of the shell and plug. F 3 is a plan view of one of the filling-blocks. Fig. el is a plan view of a modified form of fillingblock. Fig. 5 is a sectional detail of another modified form of filling-block. Fig. G is a plan view of another modified form of filling-block. v

The filling-blocks embodying my invention may be employed on the interior of Specification of Letters Patent.

the shell and also on the exterior of the plug.

Referring to Figs. 1 and 2, a represents a portion of the shell of the engine, and I) the blades, arranged on its interior; and c represents a portion of the plug, and cl t-he blades, arranged on its exterior. The filling-blocks are arranged between the blades. These blocks are composed of metal, iron or steel being preferably employed, as such material is best suited to the conditions. A metal block will not soften or become yielding by the action of the stock which passes through the engine, as it will not absorb the liquid ingredients of the stock, and when once set, so as to rigidly hold the blades, will continue to hold them. The blades in the shell are arranged more or less obliquely to the axis, and hence the filling-blocks are correspondingly arranged. The blades b are arranged in several series extending around the interior of the shell and each series comprises a plurality of short, straight blades, as shown in Fig. l, or a plurality of angularly formed blades, as shown in Fig. 4. In case the short straight blades are employed the filling blocks will likewise be made short and straight, as shown in Fig. 3, and formed with parallel ends adapting them to abut against the ends of the adjacent blocks, and in case the angularly formed blades are employed, the filling blocks will be angularly formed, as shown in Fig. Ll, being bent at a point intermediate their length. To facilitate bending the blocks they will be cut at the bending point, as at c2, V-shaped portions being removed. The filling-block of either form shown, is composed of a channel-iron bar, that is to say, it has a top or crown e and a pair of side flanges e, c, and it is arranged between the blades with its top exposed and side flanges concealed. The block is made slightly tapering from end to end, see Fig. 3, or it may be made with parallel sides, see Fig. 6. Instead of making the block of a channeled-bar, it may be otherwise formed, as for instance, it may be made solid, as shown in Fig. 5. lVhen the filling-block is used on the shell its side flanges diverge, and when used on the plug its side flanges converge, so that in either case it tapers from top to bottom.

The blocks and blades will be held assembled by means of wedges and in lieu of I L s o the usual wedges employed for this purpose l at an angle at a point intermediate its newly designed wedges are provided, see Fig. l, wherein f and f represent a pair of wedges arranged between two sections of the blocks and blades, said wedges being made with one side following` the axial direction of the plug or shell carrying them and the other side at an angle to this direction and disposed in opposite ways with their sides which follow the axial direction of the plug or shell arranged adjacent to each other and having interposed between them a blade f2, which, it will be observed, is hereby arranged to follow the axial direction of the plug or shell. ledges of this form have the advantage of holding a blade between them which so fills the space as to prevent the stock passing therethrough too freely. These wedges may be composed of metal like the filling-blocks.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. In a refining engine, a metallic fillingbloclr adapted to be placed between the blades, consisting of' a channel-iron bar, substantially as described.

2. In a refining engine, a metallic fillingblocl adapted to be placed between the blades, consisting of a channel-iron bar made tapering from end to end, substantially as described.

8. In a refining engine, a metallic fillingbloel adapted to be placed between the blades, consisting of a channel-iron bar bent length, substantially as described.

t. In a refining engine, a metallic fillingblock adapted to be placed between the blades, consisting oi a channel-iron bar made tapering from top to bottom, substantially as described.

5. In a refining engine, a metallic iillingblock adapted to be placed between the blades, consisting of' a channel-iron bar made parallel from end to end, substantially as described.

G. In a refining-engine, a metallic fillingbloclr adapted to be placed between the blades, consisting of a channel-iron bar arranged with its crown exposed and its side flanges concealed, substantially as described.

7. In a refining-engine, a pair of wedges for holding the blades and filling-blocks assembled, made with one side following the axial direction of the member carrying them, and the other side at an angle to this direction and disposed in opposite ways with their sides which fellow the axial direction of the member arranged adjacent to each other, and a blade interposed between the said wedges, substantially7 as described.

In testimony whereof, I have signed my naine to this specification, in the presence oi two subscribing witnesses.
